Ubuyobozi bwo Guhitamo Graphite Crucible ya TaC Coated

Mu bikoresho bikuramo kristale mu bushyuhe bwinshi no mu bikoresho byo mu bwoko bwa epitaxy/deposition, icyuma gikoresha grafiti gikora imirimo itatu icyarimwe: umupaka w'ubushyuhe, aho uburyo bwo gukora isuzuma bugera, n'isoko ishobora kwanduza / imbogamizi zo kwanduza. Iyi ni yo mpamvuIbikoresho bya grafiti bitwikiriwe na TaCbiri kugenda birushaho kugaragara—urwego rwa TaC rutanga ubushobozi bwo hejuru bw'ubushyuhe, kurwanya ingese cyane, no kurushaho gukumira imyanda, bigakomeza ibyiza bya grafiti mu gihe bigabanyije intege nke zayo.

1) Ni ibihe bibazo bishobora gukemurwa n'ingufu za TaC?

A. Ubudahangarwa bw'inkongi
Dufashe urugero rw'imikurire ya SiC n'imikorere ifitanye isano na epitaxy, ubwoko bufite silikoni ku bushyuhe bwinshi—hamwe na hydrogen na halogen chemistry—bishobora gutuma ibice bya graphite bikomeza kwangirika no kwangirika k'imikorere y'ibice bya graphite. Raporo z'inganda zivuga kandi ko mu kirere gikungahaye kuri silikoni kandi kiri hejuru ya 2000°C, ibyuma bya graphite bishobora kwangirika cyane nyuma y'amasaha make gusa, mu gihe irangi nka TaC rishobora kongera cyane kuramba.

B. Uduce duto twagabanutse n'ihinduka rya karuboni
Iyo uduce twa grafiti cyangwa imyimukire ya karuboni yinjiye mu gice cy’ikura cyangwa mu gace k’aho ibintu bishyirwa, bishobora kugaragara nk’ibisembwa, ibintu bivanze, ubucucike bwinshi bwo kwimuka, ndetse bishobora no gutera ubwandu budasubirwaho mu cyumba. Nk’urwego rw’inzitizi, intego ya TaC ni ugutuma ubushyuhe buhagarara neza no kudakora neza mu buryo bugenzurwa. Ubushakashatsi buri gukorwa kandi bugaragaza ko irangi rya TaC rifasha mu gukumira kwangirika kwa grafiti/kwangirika kw’imiterere no kunoza ubushyuhe mu bidukikije bikuramo kristu. ②

C. Idirishya ryagutse ry'ibikorwa
Abantu benshi bafata ibiryo by'imisatsi nk'ibintu bishobora gukoreshwa, ariko mu by'ukuri bikora nk'ibintu"moteri zitanga imiterere y'imipaka". . . ."Iyo ubuso bw'icyuma bukomeje kuba bwiza, imbaraga z'ubushyuhe n'imikorere ya gaze birushaho kugaruka. Iyo uburyo bwo gufatana kw'icyuma budahagije—bigatuma habaho uduce duto cyangwa kwinjira mu buryo busanzwe—ubusanzwe inzira ikunze gutangirira aho. Ubushakashatsi bwihariye ku mbaraga zo gufatana hagati y'icyuma na grafiti bwamaze kubiganiraho nk'ikintu cy'ingenzi bigira ingaruka ku mikurire y'icyuma kimwe.

2) Ni hehe hakwiriye cyane?

• Ikirere gifite ubushyuhe bwinshi cyane, cyangiza cyane

• Intambwe zo gukura/gukuramo zishobora kwibasirwa cyane n'uduce duto n'imyanda y'icyuma

• Imirongo ikora ibintu byinshi isaba igihe kirekire kandi ihamye

3) Uburyo bwo guhitamo TaC Coated Graphite Crucible

Gusiga TaC si inzira imwe "ikwiriye bose". Dukoresheje urugero rwa CVD, inyandiko zatanze ibiganiro birambuye ku bijyanye no gushyira CVD mu byiciro no kugena imikorere ya TaC/SiC ku bikoresho bya grafiti.

Inzira zitandukanye zitanga umusaruro utandukanye:

• Ubucucike n'ubushobozi bwo kwinjira mu kirere:Uko irangi rirushaho kuba rinini, ni ko ririnda ingese iterwa n’imyuka/umwuka ihumanya ikirere buhoro buhoro.

• Ubunini n'umuvuduko:Uko ubunini bwiyongera, ubushyuhe n'ingaruka zo kwangirika nabyo biriyongera, bisaba kugenzura neza inzira.

• Gusana no guhuza ibintu:Umusaruro mwinshi uterwa n'uko ibintu bihinduka mu buryo bungana ndetse no kumenya niba kuvugurura/gusimbuza bishobora gukorwa mu buryo bwizewe.

4) Ibipimo by'ingenzi by'igenzura ryinjira

• Isura n'imiterere y'ubuso:imyobo, imyobo, imiterere y' "ibipimo by'ibifi", ihinduka ry'ibara/imvi mu gace runaka

• Ubunini n'uburyo bungana:impande, inguni, n'aho hasi niho hashobora kuba hato cyane

• Imbaraga z'imigozi / ubudahangarwa bw'ubushyuhe:Uburyo bwo gupima busobanutse neza hamwe n'ibipimo byo kwanga/gusiba/gushaka bigomba gusobanurwa

• Uduce duto n'imyenge:(byashyizwe hamwe n'ibyavuzwe haruguru mu bikorwa)

• Kurwanya ubwandu:Imyanda y'icyuma, ibisigazwa bya halogen, n'urwego rw'isuku y'uduce byose bigomba gukurikiranwa
